MDSAL rejects valid json file when YANG model has a container that crosses a Choice

The attached files include the YANG models used and the test file I posted to the nrothbound.

To re-create, create a dummy project. put the attached files in api/src/main/yang

Build the project and POST the json file ( see attached tar.gz) to the northbound

curl -v -X PUT -u admin:admin --header "Content-Type:application/json" --data @access-control-list.json http://127.0.0.1:8181/restconf/config/ietf-access-control-list:access-lists

 Attached error.log (stdout  error returned when I use CURL to post )

Attached karaf-logs.tar.gz the server logs from Karaf. I set these to DEBUG and repeated the experiment above.
